DepWire MCP — 安装 & 实时演示

Name: DepWire MCP Server
Author: depwire

为什么要用

核心特性

Module + symbol-level dependency graph (TypeScript, Python, Go)
Reverse-impact queries (who calls / who imports)
Test coverage mapping per file
Cycle detection
Indexes update incrementally on save

安装

选择你的客户端

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "depwire-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "depwire"
      ]
    }
  }
}

打开 Claude Desktop → Settings → Developer → Edit Config。保存后重启应用。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "depwire-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "depwire"
      ]
    }
  }
}

Cursor 使用与 Claude Desktop 相同的 mcpServers 格式。项目级配置优先于全局。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "depwire-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "depwire"
      ]
    }
  }
}

点击 Cline 侧栏中的 MCP Servers 图标，然后选 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "depwire-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "depwire"
      ]
    }
  }
}

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "depwire-mcp",
      "command": "npx",
      "args": [
        "-y",
        "depwire"
      ]
    }
  ]
}

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "depwire-mcp": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "depwire"
        ]
      }
    }
  }
}

加入 context_servers。Zed 保存后热重载。

claude mcp add depwire-mcp -- npx -y depwire

一行命令搞定。用 claude mcp list 验证，claude mcp remove 卸载。

使用场景

实战用法： DepWire

Rename an exported symbol safely across an unfamiliar codebase

👤 Engineers refactoring legacy code ⏱ ~15 min intermediate

何时使用： You don't trust the codebase enough to just grep-and-rename.

前置条件

Server/skill installed and authenticated — See repo README

步骤

Map the impact

Show me every file that imports parseConfig from src/config.ts.✓ 已复制

→ List of importers grouped by package
Find covering tests

Which tests exercise src/config.ts? Run them first.✓ 已复制

→ Test files + pass/fail status
Refactor

Rename to loadConfig everywhere. Update tests too.✓ 已复制

→ Diff across all importers

结果： Rename with confidence — every call site and every test accounted for.

注意事项

Dynamic imports (require(x)) won't show up in the graph. For dynamic dispatch, double-check with grep. — Dynamic imports (require(x)) won't show up in the graph. For dynamic dispatch, double-check with grep.

搭配使用： filesystem · github

组合

与其他 MCP 搭配，撬动十倍杠杆

depwire-mcp + filesystem

Pair with filesystem for complementary capabilities

Use this server together with filesystem to complete a multi-step task.✓ 已复制

工具

此 MCP 暴露的能力

工具	输入参数	何时调用	成本
who_imports	file_or_symbol	Find the blast radius of a change	free
transitive_callers	symbol	Trace a function's full caller tree	free
tests_covering	file	Find tests to run after touching a file	free

成本与限制

运行它的成本

API 配额: See provider docs for rate limits
每次调用 Token 数: Varies by tool
费用: See repo README for pricing details
提示: Cache tool results and avoid repeated identical calls.

安全

权限、密钥、影响范围

凭据存储： Use environment variables; never commit secrets

数据出站： Tool calls go to the provider's API as documented

故障排查

常见错误与修复

no index built

Run depwire index from the repo root before first use. Re-run after major branch switches.

验证： who_imports returns results

missing files

Add the language pack (e.g. depwire lang add python) if your repo isn't pure TS.

验证： depwire status lists the language
